FOURDRINIER MACHINE.

Application filed January 11, 1915.

To all whom it mag concern:

Be it known that I, GEORGE D. KILBERRY, a citizen of the United States,residing at lVorcester,in the county of Worcester and State ofMassachusetts, have invented a new and useful Fourdrinier Machine, ofwhich the following is a specification.

This invention relates to a Fourdrinier machine in which the ordinaryshaking action does not take place.

The principal object of the invention is to provide a practicable andefficient means whereby a great amount of time is saved every time thewire is to be replaced or renewed, and whereby injury to the table rollsis avoided.

The invention also involves supporting devices or sectional tables forthe several table rolls which are movable laterally with re spect to thewhole machine for the purpose of withdrawing these rolls from the sideto permit of removal and replacement of the wire; means whereby themovable sections of the table can be accurately located in place whenremoved and returned; convenient means for introducing the rails onwhich these sections run, and other features of construction, as willappear.

Reference is to be had to the accompanying drawings in Which- Figures 1and 2 are side elevations each of a portion of a Fourdrinier machineconstructed in accordance with this invention, and Fig. 3 is a sectionalview on the line 33 of Fig. 1 showing one of the sections of the machinein end elevation.

It will be seen that the invention is shown as applied to a Fourdriniermachine of a well known type in which the Wire A passes over a series oftable rolls B. However, instead of the usual frame-work, this part ofthe machine is entirely changed in accordance with this invention andfor this purpose a bedlO is provided in one or more sectionsconstituting the supporting means for this part of the machine. On thisbed are arranged a series of stands 11, each one being provided with twosubstantially flat top surfaces 12 (except the end ones and these areprovided with one of these only). Located between these two surfaces, oratthe side of the surface when only one is present, is a Specificationof Letters Patent.

are provided with one or two rails 14, as the case may be. These railsare shown as 1n the form of channel irons and project up above the topof the stand in position. These are held apart by spacing blocks 15. Thetop surfaces of these rails constitute tracks for wheels 16. TheseWheels are arranged on a series of table sections 17 the legs of whichnormally rest on the surfaces 12. Each of these table sections isdesigned for supporting a plurality of table rolls B mounted in ballbearings 18 thereon for this purpose.

The rails 14 are capable of a slight motion up and down in sockets orguides 13 and for this purpose each of the stands is provided with avertically moving rod or pin 18 having a plate 19 on the top forsupporting the bottoms of the rails 14. On the base 10 is provided a cam20 for each of these pins 18, arranged in position to engage the bottomof the pin and raise it when the cam is turned on its axis by'means of ahandle 21. The table sections 17 are provided with pins 22 for enteringholes in the surfaces 12 for locating the table sections in properposition. For supporting the table' sections when withdrawn from themachine rails 21 are provided similar to the rails 14:. One of each isarranged to rest in one of the sections and the other has a support 23.

In order to provide conveniently for the introduction of the heavy rails11 whenever the endless Wire is to be replaced, the following mechanismis shown: Mounted to swing on the axes of studs 25", are a series offrames 25, one located at each end of each pair of'rails and havingrollers 26 on their ends. These are capable of swinging around to theposition shown in Fig. 3, for the purpose of supporting the rails at adistance from their ends while being introduced into After the rails areintroduced, frames 25 are swung out to one side, as shown in Fig. 1 toget them out of the way.

The drawings show the usual deckle strap 27 and wash trough 28 for it.The frame 29 for the-wash trough is supported by one of the tablesections. Although I have not shown the entire machine, it will beunderstood that the breast roll 30 is also mounted on one of these tablesections and moves out with it, the operation being the same as thatdescribed above, but the track is raised by a screw 31. a

quently, all the usual injury to them and The operation of moving thetables so as to supply or replace a wire will be understood from whathas been said, the wire being let down at the bottom by slackening upthe adjusting drums as 32 so as to form loops that pass below the levelof the surfaces 12. The rails 14 are raised and the several tablesections drawn out on the rails 21 which are in place. The wire is thenreplaced readily with practically no difficulty, it being supported bythe usual rolls or cylinders not shown herein. Then before it istightened up and while its parts form loops below the level of thesurfaces 12 the table sections are moved in by hand. WVhen the pins 22register with their perforations in the tops of the stands thes'e pinsare allowed to drop into these perforations and the pins 18 are loweredby turning the handles 21. This brings the bottoms of the tables down onthe surfaces 12 and relieves the wheels of their weight. The rails arethen removed and preferably the rails 14 are withdrawn and laid asideuntil needed again.

' The wire is tightened by the usual adjusting drums.

In this way a very material saving in time and cost is accomplishedevery time the wire former has to be renewed and this is an importantresult in this class of machines because a very material loss of timehas been necessary heretofore. Another important advantage lies in thefact that by this arrangement, a section of rolls are removed tbgetherwithout Consetheir journals is absolutely avoided.

Although I have illustrated and described only a single embodiment ofthe invention, I am aware of the fact that many modifications can bemade therein by any person skilled in the art without departing from thescope of the invention as expressed in the claims. Therefore, I do notwish to be limited to all the details of construction herein shown anddescribed, but

What I.do claim is 1. In a Fourdrinier machine, the combination of aframework, rails supported thereby under the top thereof, a framepivoted adjacent to said rails on an upright the wheels and lifting thetable off said supporting surfaces.

3. In a Fourdrinier machine, the combination with a series of standslocated opposite each other on the side of the machine,

each stand having a supporting surface at the top, a plurality of tablesections having legs by which they are adapted to be supported on saidsurfaces and adapted to carry table rolls, and means whereby they can bewithdrawn from position laterally without contacting with said surfaces.

4. In a Fourdrinier machine, the combination of a frame havingoppositely located sockets therein, a rail supported in two of theopposite sockets and movable up and down therein, a pair of pins forcarrying said rails, and cams for raising said pins and rail.

5. In a Fourdrinier machine, the combination of a frame having socketslocated oppositely for supporting rails, a frame pivoted adjacent to oneof said sockets on an upright axis, and a wheel on the frame adapted toassist in supporting the tracks when the frame is swung inwardly.

6. In a Fourdrinier machine, the combination of a base, transverse railsremovably mounted thereon, sectional tables for supporting rolls adaptedto move on said rails, and additional rails placed at the ends of thefirst named rails; for receiving the tables at one side of the machine.

In testimony whereof I have hereunto set.

my hand, in the presence of two subscribing witnesses.
